//    (strictly speaking the preload scannner) starts preloading the image,
//    and the image url takes some time for loading,
// 2. <img> loads the same URL and renders the partial image after some image
//    data is received but before fully loaded, and then
// 3. the image is loaded and integrity check is done.
